Trap: Confusing 'Ramsar sites' with 'UNESCO World Heritage Sites' — Ramsar Convention is on Wetlands (Iran, 1971), not UNESCO.
Most confused: The difference between a Ramsar site's 'ecological character' and its 'Ramsar criteria' — criteria determine designation, character determines management obligations.
Key anchor: India's Ramsar site count has grown rapidly — from 26 in 2014 to 85 by 2026. The examiner wants you to understand why this growth happened (political will, simplification of designation process) and what it means (more sites = more management responsibility, not just a number).
Current affairs hook: 2026 new additions to Ramsar list; Chilika Lake's management model; the ongoing debate on the 'Wetland Rules 2017' and their dilution; the Namami Gange programme's wetland component.
Mains hinge: Wetland conservation is best linked to water security (groundwater recharge), biodiversity (migratory birds), and livelihoods (fisheries). A good answer shows that wetlands are 'not wastelands' — a mindset the government is trying to change through the Wetland Rejuvenation Programme.
Core Concept
Wetlands are defined by the Ramsar Convention as "areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt." They are among the most productive ecosystems on earth, comparable to rainforests and coral reefs.
The Ramsar Convention (1971)
Adopted in the Iranian city of Ramsar on the shores of the Caspian Sea, the Convention on Wetlands of International Importance (the Ramsar Convention) is the oldest international environmental treaty. India is a signatory and has designated 85 wetlands as 'Ramsar sites' — the highest in South Asia and among the top five globally. Key obligations under the Convention:
Designate suitable wetlands for the List of Wetlands of International Importance
Maintain the 'ecological character' of listed sites
Promote 'wise use' of all wetlands in national territory
Cooperate internationally on transboundary wetlands and shared species
India's Ramsar Sites: The Growth Story
India's Ramsar count has grown explosively in the last decade. In 2014, India had 26 sites. By 2022, that number crossed 50. By 2026, it stands at 85. This growth is attributed to:
The under the Environment Protection Act, which created a regulatory framework for wetlands
The National Plan for Conservation of Aquatic Ecosystems (NPCA) — a centrally sponsored scheme
State-level efforts — particularly from Tamil Nadu, Uttar Pradesh, and Gujarat, which have designated many smaller wetlands
The Wetlands Rejuvenation Programme under the National Mission for Clean Ganga (NMCG)

Largest lake in Kerala; backwaters tourism; Kuttanad below-sea-level farming
Ashtamudi Wetland
Kerala
Second Ramsar site in Kerala; known for clam fisheries
Sambhar Lake
Rajasthan
India's largest inland salt lake; important for migratory flamingos
Threats to Wetlands
Encroachment and land-use change: Urbanisation, agriculture, and infrastructure projects are the biggest drivers of wetland loss. The 'Wetland Rules 2017' were diluted after complaints from states that they hindered development.
Hydrological alteration: Dams, barrages, and canal networks disrupt natural water flows into wetlands. The Ganges river system's barrages have significantly affected the ecoregion's wetlands.
Pollution: Industrial effluents, agricultural runoff (pesticides, fertilisers), and untreated sewage degrade water quality. Loktak Lake faces severe eutrophication.
Invasive species: Water hyacinth (Eichhornia crassipes) is the most widespread invasive in Indian wetlands, choking water bodies and reducing oxygen.
Climate change: Rising temperatures, altered rainfall patterns, and sea-level rise threaten coastal wetlands. The Sundarbans are particularly vulnerable.
Conservation Approach: The 'Wise Use' Concept
The cornerstone of the Ramsar Convention is 'wise use' — defined as "the maintenance of the ecological character of wetlands, achieved through the implementation of ecosystem approaches, within the context of sustainable development." This is not a preservationist approach; it recognises that human use of wetlands is legitimate but must be sustainable.
India's approach under the Wetland Rules 2017:
Wetland Authority — each state must establish a State Wetland Authority
Wetland Inventory — comprehensive mapping and classification of wetlands
No-go zones — activities like conversion, encroachment, and discharge of untreated effluents prohibited
Wetland Health Cards — an innovative approach to regular monitoring (piloted by NMCG)
Key Facts
Ramsar Convention adopted: 2 February 1971 (World Wetlands Day)
India's Ramsar sites: 85 (as of 2026)
First Ramsar sites in India: Chilika Lake (Odisha) and Keoladeo National Park (Rajasthan) — 1981
Highest number of Ramsar sites in India: Tamil Nadu (18 sites)
Total wetland area in India: ~15.26 million hectares (4.6% of India's land area, as per ISRO's Space Applications Centre)
Inland wetlands dominate: 69% are natural; 31% are man-made (reservoirs, tanks)
India has 19 wetlands of 'International Importance' beyond Ramsar sites
Montreux Record: Sites where ecological character has changed/is changing — only Keoladeo National Park (since 1990) and Loktak Lake (since 1993) from India
Chhota Nagpur Plateau: Highest density of wetlands in India
The term 'Ramsar' is a city name, not an acronym
